BLOCK-SETTING MECHANISM FOR BALING PRESSES.

To all whom it may concern:

Be it known that I, ALBERT GRIEVES, a

citizen of the United-States, residin at ful Improvements in Block-Setting Mechanism for Baling Presses, of which the following is a full, clear, and exact specification. 1

This invention relates to baling presses, and more particularly to block setting mech anism for baling presses.

In presses employed for baling hay and like material, it is customary to interpose blocks between the adjacent bales, the blocks having cutaway portions adapted to receive the baling wire with which the bale is bound. If the press is to be efficient and successful in operation, it is necessary that the blocks be placed in position in the block setting mechanism, and be transferredfrom the block setter to the baling chamber of the press easily and expeditiously.

The present invention has for its object, therefore, to provide a construction of setter in which a block may be easily, quickly and accurately positionedand from which the block may be discharged by any'suitable means when desired. l

In carrying out the objects above noted, I have in the present instance provided a manually operable block setter, the setter having means for retaining the block in position, this retaining means being operable to release the block when the block is engaged by a moving member carried in this instance by the feeder head. The block retaining member may be normally maintained in a position to limit the movement of theblock, by resilient means, and in the particular construction illustrated, means has been provided for co-operating with this block retaining member when theblock setter is in its normal or inoperative position to limit the outward movement of the retaining member, thereby limiting the position into which the block may be forced by the operator of the machine,

In the embodiment of the invention illustrated in the drawings Fi lcshows in side elevation a portion of a being press, having my improved block setter thereon;

The baling press, in connection with which my invention is illustrated, is the ordinary plungertype of press, having upper and lower side frame members 10 and 11, and having side members 12 (one of which is illustrated) for enclosing the baling chamber. A feeder head 13is provided for feeding the hay into the baling chamber, this head being actuated by feeder arms 14 connected in any suitable manner to the driving mechanism. The head 13, as illustrated, is provided with a resilient outwardly projecting member 15 adapted to engage the block when the block setter has been moved to operative or block setting position and to force the block into the baling cham- 1 pivoted to a frame'in a, manner described below.

A pair of bracket members 16, substantially triangular in outline, is secured by any suitable means to the said frame memmembers form the support for the block setter, and also serve as guidesfor the block setter as the setter is swung about its pivot. As illustrated'mor e'particularly in bers 10 of the baling press. These-bracket 3, the brackets 16 are provided at their upperends with inwardly projecting flanges 17, forming,-with offset portions 18 of the brackets, channels for the reception of lugs carried by the block retaining membersyas hereinafter described. The lblock' setter comprises a pair of L-shaped brackets 19 pivoted at 20 to the brackets. 16,and each supporting on its upper surface an angle tree at re e ving member 2 the mem ers receiving the block 22, as illustrated in Figs. 1, 2 and 4. The members 21 are connected together and braced by means of transverse members 23 and 24, the member 2 1 being extended beyond the outer surfaces of the members 21, and being provided with apertures 25. A pair of arms 26 is secured to the rear ends of the members21, and these arms form a support for the block setter, when the setter is in its normal position, by the engagement of the lower ends of its arms with the upper surfaces of the side frame members 10 of the press. As illustrated in Fig. 1, the arms are extended above the block setter to form handles 27, by means of which the setter may be manually swung on its pivots 20 t0 a block set-ting position. In connection with my improved block setter, I have provided resilient means for retaining the block in position in. the setter, this means comprising a pair of substantially flat metallic strips 28, having journal brackets 29 secured at their rear ends. The brackets 29 are pivoted on pins 30 oarriedby the members 26, as clearly illustrated in Fig. 1. These brackets also are provided with recesses 31 for the reception of a laterally extending upper end portion 32 of a pair of clips 33, which extend downwardly, passing through the apertures 25 in the member 2 1. The clips 33 are provided at their lower ends with nuts 34:, and intermediate the nuts 3 and the lower surface of the outwardly extending portions of the transverse member 2% there are provided spiral compression. springs As illustrated in Fig. 1, these springs exert a downward force on the clips 33, thereby forcing the member 28 downwardly into engagement with the upper surface of the block 22. The members 28 are provided on their free ends with downwardly extending or off-set portions 36 which limit the inward movement of the block 22, and these members are also provided with laterally extending lugs 37 which in the normal position of the block setter project into the channels formed by the portions 17 and 18 of the brackets 16. From the above de scription it will be seen that the port-ion 17 of thebrackets normally limit the upward movement of the members 28, thereby retaining these members in operative position of the block setter in the position shown in Fig. 1. Since these members are retained in this position, the inward -movement of the block 22'is limited, and the block is prevented from extending through the block ing injury to the machine and possibly serious damage to the feeder head. Means has also been provided on the brackets 19 for limiting the movement of these brackets about their pivots 20, this means comprising laterally projecting lugs 38 which engage the rear edges 39 of the brackets 16 as the block setter is swung to the dotted line position shown in Fig. 1.

Ltis believed that the operation of the device above described will be clear, but a brief statement of the operation will be given. When the block setter is in a normal or inoperative position, shown in full lines in Fig. 1,-a block may be inserted by merely placing the block in the rear end of the setter in the block supporting members 21, and forcing the block into the setter as far as possible. The block will then be located in its proper position, and since the lugs 3T are in engagement with the channels in the brackets 16, the outward movement of the members 28 is limited and therefore the offset ends 36 definitely limit the inward movement of the block. The operator therefore need exercise no special care in inserting the block. When a suflicient amount of material has been fed into the baling chamber to form a bale, the block setter is swung to the position shown in dotted lines in Fig. 1, and during this operation the lugs 37 pass out of the channels in the brackets 16, thereby releasing the members 28 for movement about their pivots when the block is engaged by the member 15 carried by the feeder head. It will be understood that the springs 35 are of sufficient strength to retain the members 28 in the normal position shown in Fig. 1, in which position the block is held in the block setter until the block is forced downwardly by means of the engagement of the block by the feeder head.

From the above specification setting forth the construction and operation of my improved block setter, it will be seen that I have provided a simple and efiective construction, a construct-ion adapted to receive the block and to retain it in position without the exercise of undue care by the operator, and also adapted torelease the block when the setter has been swungto a position in which the block may be engaged by the block discharging member.
